HEATING-DRUM OR SPARK-ARRESTER.

SPECIFICATION forming part of Letters Patent No. 374,436, dated December6, 1887.

Application filed July 12, 1887. Serial No. 244,113. (No model.)

To all whom it may concern:

Be it known that I, URIAH J. WAKEMAN, a citizen of the United States ofAmerica, residing at Big Rapids, in the county of Mecosta and State ofMichigan, have invented certain new and useful Improvements in Heating-Drums or Spark-Arresters, of which the following is a specification,reference being had therein to the accompanying drawings.

This invention pertains to certain new and useful improvements inheating drums or spark-arresters; and it consists in the detailedconstruction, combination, and arrangement of the parts, substantiallyas hereinafter fully set forth, and particularly pointed out'iu theclaims.

In the accompanying drawings, Figure 1 is a View in perspective of myinvention with parts broken away, and Fig. 2 is a similar View showingthe drum or casing in dotted lines.

This invention is designed to be applied to a stove-pipe of any ordinarycooking or heating stove, or to any smoke-stack, &c.

In carrying out my invention I employ a long cylinder or drum, A, theend and cap of which are approximately cone shape and taper into narrowextensions for fitting to the stovepipe. WVithin this cylinder or drum Aare disposed three or more circular plates, the upper and lower ones,aa, of which fit snugly against the inner surface of the cylinder ordrum, as shown, while a narrow space is left between thecentrally-disposed plate a" and the cylinder or drum. These plates areconnected together. by and secured to three or more vertically-disposedrods, 1) Z), the upper ends of which are threaded and provided with nutsfor retaining the same in position. Each circular plate has a centralaperture, 1), formed therein, the aperture in the plate at having adamper, 6, working therein, the same being controlled by ahorizontally-disposed handle,

' O, projecting beyond the cylinder or drum.

This handle of the damper I) is held in place by suitable keepers, andis passed through an eye formed by a piece of metal struck out from thecenter of the damper.

D is a spai'loarrester disposed on the upper circular plate, a,over thecentral opening therein, said spark-arrester being made of wire screen,circular in horizontal section at its center,and ofapproximatelyinvertettU shape in vertical section.

From what has been said it will be seen that the current of air willcause the sparks on entering the lower end of the cylinder or drum topass in the direction of the arrows w, and until the fire in the stovefrom which the sparks are egressing is sufficiently started or under waythe damper b is caused to occupy a vertical position, permitting thesparks and smoke to pass through the opening or aperture of the centralplate, (L2, and on out through the coneshaped top of the drum.

After the fire is sufficiently started, the

damper is turned into a horizontal position,-

causing the sparks and smoke to pass in the direction of the arrows 1and up around the sides of the central plate against the inner surfaceofthe cylinder or drum, and upon passing through the aperture in theupper 7 plate, a, the sparks are prevented from passing out through theupper end of the drum by reason of the wire screen D before described,while the smoke passes on out through the upper end of the drum into thestove-pipe.

My invention comprises siinpleaud effective means for retaining for alimited time the heat passing from the stove to, the pipe of which myinvention is attached, and also prevents the sparks from the fire frompassing through the drum into the upper pipe, which frequently causesfire and resulting damages.

1 claim as my invent-ion- 1. The herein-describedheatingdrun1,comprising the cylinder or drum having come shaped ends,the circular plates connected by rods and having central apertures, themiddlesmaller one ot'which plates is provided with a damper, and thewire screen spark-arrester disposed over the central aperture in the topone of said plates, all constructed and arranged substantially as shownand described.

2. The combination, with the cylinder or drum, of the series of circularplates disposed therein and having central apertures, the central one ofsaid plates being smaller than the others and having a damper working inits central aperture, substantially as shown and 5 described.

3. The combination, with the cylinder or drum having the coneshapedends, of the circular plates having central apertures, the nutted rodsconnecting said plates, the damper 10 working in an aperture of thecentral smaller one of said plates, and the spark-arrester disposed onthe. upper surface of the topmost plate-over the aperture thereof,substantially as shown and described.

In testimony whereof I affix my signature in {5 presence of twowitnesses.
